Neighbours described their horror after an "explosion" rocked a housing estate in the Huyton area.
Residents said they felt their "house shake" and "didn't feel safe in their own homes" after the incident in Pennard Avenue this afternoon. According to reports, a boy came rushing out of a terraced property covered in blood while an elderly woman who lived in the same house fainted.
Police confirmed a 12-year-old boy was taken to hospital with injuries to his head and body after a firework was set alight at around 2.45pm. Officers from Merseyside Police and Merseyside Fire and Rescue (MFRS) have launched an investigation.
